Code Signing is a process to confirm the authenticity and originality of digital information, especially software code, and assuring that this digital information is valid and additionally establishes the legitimacy of the author. Code signing creates a hash of the code and encrypts it with a private key adding its signature. It also establishes assurance that the code has not changed or been revoked after it has been signed by the signature. Public Key Infrastructure systems can also use code Signing Solution to ensure the security of their certificates.
